First Embodiment

Referring to FIG. 1 to FIG. 3, a first embodiment of the present disclosure is illustrated. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.

The present embodiment discloses a spring mattress with a softness adjustable mechanism. The spring mattress includes an upper mattress body 1, a lower mattress body 2, a plurality of springs 3, and a plurality of softness adjusting units 4. The spring mattress can also be covered by a covering body (not shown). The covering body is well known to one skilled in the art and need not be reiterated herein.

The upper mattress body 1 and the lower mattress body 2 each is a sheet-like body. The lower mattress body 2 is disposed below the upper mattress body 1, and the upper mattress body 1 is spaced apart from the lower mattress body 2, such that an accommodating space 21 is formed between the upper mattress body 1 and the lower mattress body 2. The accommodating space 21 is capable of accommodating the springs 3 and the softness adjusting units 4.

The springs 3 may be compression springs. The springs 3 are preferably subjected to a rustproof treatment so that a surface of each of the springs 3 is coated with an oxidation resistant layer by baking or blackening. The rustproof treatment to the springs 3 is well known to one skilled in the art and need not be reiterated herein. The springs 3 are disposed in the accommodating space 21. The springs 3 are located between the upper mattress body 1 and the lower mattress body 2, and the springs 3 are spaced apart from each other. That is, the springs 3 are arranged in a matrix and are disposed between the upper mattress body 1 and the lower mattress body 2 at intervals. The number of the springs 3 is not limited to those shown in the drawings and may be appropriately increased or decreased according to actual needs. One end of each of the springs 3 may abut against the upper mattress body 1 or the lower mattress body 2. In the present embodiment, one end (i.e. upper end) of each of the springs 3 abuts against the upper mattress body 1.

Referring to FIG. 4 to FIG. 5, each of the softness adjusting units 4 may include various automatic or manual adjusting components such as an airbag, a pneumatic cylinder, a hydraulic cylinder or a motor screw. In the present embodiment, each of the softness adjusting units 4 includes an airbag 41. As shown in FIG. 7, the airbags 41 of the softness adjusting units 4 are connected to an air pump 8 through pipes (not shown) such that the air pump 8 is capable of inflating or deflating the airbags 41 of the softness adjusting units 4 through a control unit 9. The airbags 41 of the present embodiment are inflated in a low pressure manner, which is safer. In another embodiment of the present disclosure, the air pump 8 can be operated manually to inflate or deflate the airbags 41. The softness adjusting units 4 are disposed in the accommodating space 21. The softness adjusting units 4 are located between the upper mattress body 1 and the lower mattress body 2, and the softness adjusting units 4 are spaced apart from each other. That is, the softness adjusting units 4 are arranged in a matrix and are disposed between the upper mattress body 1 and the lower mattress body 2 at intervals. The number of the softness adjusting units 4 is not limited to that shown in the drawings and may be appropriately increased or decreased according to actual needs. All of the springs 3 can respectively correspond in position to the softness adjusting units 4, but the present disclosure is not limited thereto. For example, in another embodiment of the present disclosure, only some of the springs 3 respectively correspond in position to the softness adjusting units 4.

More specifically, the softness adjusting units 4 may be respectively disposed below or above the springs 3. The softness adjusting units 4 may respectively abut against the springs 3. That is, one end of each of the softness adjusting units 4 may respectively abut against the other end of each of the springs 3, and the other end of each of the softness adjusting units 4 may abut against the lower mattress body 2 or the upper mattress body 1. In the present embodiment, the softness adjusting units 4 are respectively disposed below the springs 3, one end (i.e. upper end) of each of the softness adjusting units 4 respectively abuts against a lower end of each of the springs 3, and the other end (i.e. lower end) of each of the softness adjusting units 4 abuts against the lower mattress body 2.

In the present embodiment, each of the springs 3 and the corresponding softness adjusting unit 4 are sleeved by a retractable sleeve 5. The retractable sleeves 5 each include an inner sleeve 51 and an outer sleeve 52 in which the outer sleeve 52 is partially sleeved outside the inner sleeve 51, and the inner sleeve 51 is movable relative to the outer sleeve 52. In each of the retractable sleeves 5, an upper end of the inner sleeve 51 is connected to the upper mattress body 1, and a lower end of the outer sleeve 52 is connected to the lower mattress body 2, such that the retractable sleeve 5 is connected between the upper mattress body 1 and the lower mattress body 2. More specifically, each of the springs 3 and the corresponding softness adjusting unit 4 are disposed in the corresponding retractable sleeve 5 such that the retractable sleeve 5 is capable of supporting and fixing the spring 3 and the softness adjusting unit 4. The inner sleeves 51 and the outer sleeves 52 each have a pressure relief hole (not shown) such that if the airbag 41 accidentally bursts, the gas can be smoothly discharged via the pressure relief hole.

Further, in each of the retractable sleeves 5, a lower end of the inner sleeve 51 is provided with a first positioning portion 53 that protrudes from an outer wall of the inner sleeve 51 and extends away from an axial direction of the retractable sleeves 5; an upper end of the outer sleeve 52 is provided with a second positioning portion 54 that protrudes from an inner wall of the outer sleeve 52 and extends toward the axial direction of the retractable sleeves 5, such that when the inner sleeve 51 and the outer sleeve 52 move relative to each other to extend to a predetermined length, the first positioning portion 53 abuts against the second positioning portion 54 (as shown in FIG. 5) so as to fix in position the retractable sleeves 5 at the predetermined length.

More specifically, each of the softness adjusting units 4 is capable of being extended and retracted to change a length and an amount of compression of the corresponding spring 3. When the softness adjusting unit 4 is extended (as shown in FIG. 5), the spring 3 is compressed, the amount of compression of the spring 3 is increased, the length of the spring 3 is decreased, the elasticity of the spring 3 is decreased, and the structure of the spring 3 becomes rigid. Conversely, when the softness adjusting unit 4 is retracted (as shown in FIG. 4), the stress of the spring 3 is released, the amount of compression of the spring 3 is decreased, the length of the spring 3 is increased, the elasticity of the spring 3 is increased, and the structure of the spring 3 becomes loose.

In addition, the softness adjusting units 4 are electrically connected to the control unit 9, and the softness adjusting units 4 are respectively controlled by the control unit 9 as shown in FIG. 7. The control unit 9 is a control circuit including an IC board, and the control unit 9 is capable of controlling the softness adjusting units 4 so as to adjust the softness of the spring mattress.

In one embodiment, the softness adjusting units 4 can be adjusted to have different softness, respectively. For example, when the spring mattress is a double-bed mattress, the softness adjusting units 4 located at the left and right halves of the spring mattress can be respectively adjusted to have different degrees of softness such that the spring mattress can have two or more degrees of softness at the same time.

In one embodiment, the spring mattress can be mounted with a plurality of massagers (not shown) according to actual needs. The massagers can be controlled by the control unit 9 to set the mode and time of the massage. For example, the massagers can be set to automatically vibrate at a predetermined time to improve blood circulation and sleep quality of a user during sleep.

In one embodiment, referring again to FIG. 2 and FIG. 3, a portion of the spring mattress can also have an angle adjustable mechanism. More specifically, the spring mattress further includes a movable body 6. The movable body 6 is disposed between the upper mattress body 1 and the lower mattress body 2, and the movable body 6 can be adjusted to have different elevation angles according to actual needs. The movable body 6 is connected to a driving device 7. The driving device 7 may be a pneumatic cylinder, a hydraulic cylinder or a motor screw. The driving device 7 is configured to push the movable body 6 to have different elevation angles.

Second Embodiment

Referring to FIG. 6, a second embodiment of the present disclosure is illustrated. The spring mattress of the present embodiment is substantially the same as that of the first embodiment, and the differences are described below. The softness adjusting units 4 are respectively disposed above the springs 3, a lower end of each of the springs 3 respectively abuts against the lower mattress body 2, a lower end of each of the softness adjusting units 4 respectively abuts against an upper end of each of the springs 3, and an upper end of each of the softness adjusting units 4 respectively abuts against the upper mattress body 1. The softness adjusting units 4 of the present embodiment are also capable of being extended and retracted to change the length and amount of compression of the springs 3 so as to adjust the softness of the spring mattress according to actual needs.

The advantages of the present disclosure are that the softness adjusting units are capable of being extended and retracted to abut against the springs. When the softness adjusting units are extended, the springs are compressed, the elasticities of the springs are decreased, and the structures of the springs become rigid. Conversely, when the softness adjusting units are retracted, the stresses of the springs are released, the elasticities of the springs are increased, and the structures of the springs become loose. Accordingly, the softness of the spring mattress can be easily adjusted according to actual needs so that the applicability of the spring mattress can be improved.
